Politicians talk a lot. In fact, it's most of what they do. They talk all day, all year, decade after decade. Words are to politicians what spanners are to mechanics - tools of the trade.

Given that talk is central to their jobs, you'd imagine they might be a bit better at it. Why is it that so much of what they say is evasive? Why so many rehashed sentences? Why so many words that fill a gap, but have no clear meaning?

Because, perhaps, clear statements of truth and fact are not an option, given our current circumstances.
